ok so i been having some issues after my turbo swap,, been getting the p2187 code so i been searching for leaks for a while and no luck.. but this morning i realized i swaped the nozzles for the meth and put a bigger one so i just wanted to check if it was tight.... so i tightened it up a bit and cleared the code it had and now the car runs like ****. air fuel stays at 18 and the car bucks like crazy.... So you guys think that had something to do with it?? it wasnt that loose probably needed another half turn..

 

which kit do you have??

do you have check valve on the line connected to the nozzle? it's possible the ball inside check valve is stuck?

 

aem kit, and the valve is integrated with the nozzle
